GAZM160T4 - 4P 160A METAL ENCLOSED ISOLATOR

Why Choose the GAZM160T4?

The Lovato GAZM160T4 switch disconnector is supplied in a robust IP65 metallic enclosure with a rotating red/yellow handle for clear on/off indication. This four-pole enclosed unit is rated 160 A for AC applications. The enclosure measures 200x300x120mm (7.9x11.8x4.7''), providing a compact footprint for space‑constrained installations while delivering dependable isolation performance for panels, machinery and general industrial environments.

Engineered for demanding isolation duties, the unit offers Ui 1000 V and Uimp 8 kV, with AC21A 160 A up to 690 V and AC23A 125 A at 400 V. Conditional short‑circuit current is 50 kA with gG160 fusing, plus 1250 A making and 1000 A breaking at AC23A 400 V. Durable construction delivers 30,000 mechanical cycles and 1,500 electrical cycles, operating from −25 to +55 °C up to 3000 m.
